CREAM-SEPARATOR.

Specification of Letters Patent.

Patented Dec. 8, 1914.

1 Application filed March 23, 1914. Serial No. 826,531.

To all whom it may concern Be it known that'I, FRANK A. F ALK, a citizenof the United States, residing at Stacyville, in the countyof Mitchelland prevent the mixture of the cream with the -heavier portions of themilk after the separation of the cream therefrom.

My invention further relates to various improvements in separatorconstruction, for the purpose of improving the general efficiencythereof.

Reference is made to the accompanying drawings forming ,a part of thisspecification, and in which like letters indicate like parts.

Figure 1 is a vertical cross section through my improved creamseparator, and is taken upon the line 11 of Fig. 1, looking in thedirection of the arrow. Fig. 2 is a detail view, showing in sideelevation a guiding liner, forming a part of my device. Fig. 3 is asection, on .the line 33 of Fig. 1, looking in the direction of thearrow. Fig. 4 is a section, on the line 44: of Fig. 1, looking in thedirection of the arrow.

A. driving shaft 5, engaging a bearing 6, is provided wlth a reducedportion 7 and with a shoulder 8. Encircling the ortion 7 1s a sleeve 9,the upper portion 0 which fits upon the shoulder 8 in order to preventrelative rotary movement between'the shaft and the sleeve.

The sleeve 9 carries a number of ribs 10 extending along its generallength. Encircling the sleeve 9 are a number of linersll, each providedwith a slanting portion 12 and with a flat peripheral annular portion13. The liners are also severally provided with slots 14, these slotsalternating with the ribs. I

Each dome 11 .carries a number of eyelets 15, and is provided with aslot 16 extending through the wall of the eyelet and merging into theopen area thereof, as in dicated in Fig. 4. Each eyelet 15 is furtherprovided with a notclrlfi, for slidably engaging some one of the ribs10. The sleeve 9 also carries a bottom plate 17 which is of greaterthickness than the liners 11 and forms the bottom of the separator. Thisbottom is provided with an upwardly extending edge 18.

A casing Wall 20 is provided with a neck portion 21, the latter having ahole 22 extending radially outward. Located in the upper portion of thecasing wall 20 is a liner 28, provided with a number of. radiallyextending guiding ribs 24, as may be understood from Fig. 3. The guidingliner 23 is provided with a neck portion 25, the latter having acomparatively thick annular edge 26. A hole 27 extends through thisannular edge and also th ough the adjacent neck portion 21. The sleeve 9carries a thimble 28, the upper'end of which is threaded externally. Thethimble 28 is provided 'withholes 28 in this instance three in number.Fitted upon this threaded portion is an annular 'nut 29.

In assembling. the parts, they are a'rranged as indicated in Fig. 1.First, the various liners 11 are stacked one upon the other, the variouseyelets 15 being alined, as shown in said figure, so as toconstitute-virtually three tubes of composite form. In

doing this, the various slots 14 are brought into registry. The liners11 may be placed in position one at a time, the ribs 10, fitting intothe notches 16 (see Fig. 1), serving to properly guide the liners 11 andprevent them from turning relatively to the sleeve 9.

The neck 25 carries three elbows 30, extending radially outward from itand also extending downwardly. These elbows are adapted to register withthe eyelets 15, and also with the holes 28 as may be understood fromFig. 3. The parts being assembled, and the annular nut 29 beingtightened, the various liners are held in proper registry with eachother;

The operation of my device is as follows: Milk is poured into thethimble .28, and passes outwardly and downwardly through the elbows 30,into the composite tubes which are made up of the eyelets 15. Rotarymotion being applied to the shaft 5, the sleeve 9 and parts carried byit are caused to rotate. The milk passes downwardly in They next passupwardly and under guid-.

ance of the guiding liner 23, and ribs 24 flow into the neck portion 21and thence outwardly through the hole 22, being thus discharged from themachine. The cream, however, because of its lightness, hugs closelyaround the sleeve 9, and flows upwardly through the slots 14, asindicated in Fig. 1. Passing upwardly between the neck 25 and thethimble 28, the cream makes its escape from the opening 27.

It is impossible for the cream and heavier portions of the milk toreunite within the machine, after being separated.

I do not limit myself to the precise mechanism shown,'as variations maybe made therein without departing from the spirit of my invention.Neither do I limit myself to any single use for the separator, as it maybe employed in separating various liquids, and portions of the sameliquid having different specific gravities.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is as follows:

1. In a separator bowl, the combination of an axially rotatable stemhaving an upper inlet thimble and a plurality of elbows extendingtherearound and depending from, and communicating with, the saidthimble,

said stem and forming separate vertical milk inlet passages registeringand communicating at their upper ends with the said inlet elbows, saidliners also having registering openings immediately around the stem andforming cream passages, and means forming separate outlets for the creamand skim milk, all substantially as described.

2, In a separator bowl, the combination of an axially rotatable stemhaving an upper inlet thimble and a plurality of depending elbowscommunicating with the thimble,

a plurality of liners superposed in spaced relation around the stem. andhaving registering eyelets forming separate vertical milk inlet passagesregistering and communicating at their upper ends with the said elbows,said eyelets having side slots whereby to communicate with the spacesbetween the several liners, and said liners also having registeringopenings immediately around the stem and forming vertical creampassages, and means forming separate outlets for the cream and skimmilk, all substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
